CLEANING COMPOSITION.

No Drawing.

This invention relates to improvements in.

cleaning compositions and is particularly designed for cleaning hats of every deserlption. leather gdods, gloves and the like, white a fabrics and also for bleaching straw and Panama hats.

The primary object of the invention is to provide a very efiicient and easily prepared composition of this character which will be In non-inflammable, antiseptic, and which will not injure theskin of the person applymg the same.

The invention also aims to produce a cleaning composition, as characterized above,

II- which will not injure the material to be cleaned or leave the same in a slightly discolored condition.

The component ingredients hereinafter namedproduce the composition in its best form so far as we are now aware, but these in- ,rrredients may be varied slightly in proportions and general character without departing from the spirit and scope of the invention as claimed hereinafter.

l The best or preferred form of the invention 'cOnSists of a composition as follows:

Lead acetate Two ounces.

- Oxalic acid Three oun-"es.

Hydrogen peroxide Three ounces.

* Sulphur Four ounces. Sodium carbonate Four ounces. Rock alum Two ounces. Baking soda Two ounces.

Sodium sulphite One-half pound. Perfume One teaspoonful. \Vater One gallon.

I have found that the best mode of preparing the composition consists in first, heating the water in a suitable container to a temperature of about 100 F. The sulphur is then stirred in. making sure that all lumps are broken up. The remaining ingredients are next added in the order named the stirring being continued and the ingredients being put in at intervals. The order of deposit of the ingredients in the water is.oxalic acid, lead acetate, sodium carbonate, bicarbonate 'of soda, sodium sulphite, rock alum, hydrogen 5U peroxide and perfume.

After the ingredients have all been placed in the water and the mixture thoroughly stirred so as to dissolve any lumps or particles, the mixture is poured out into containers Serial No. 141,430.

which are corked tight. The preparation should be allowed to set about twenty-four hours before using and best results are secured by keeping the bottled preparation in a cool place out of the sunlight.

The preparation has been found to be very effective in practical use. In connection with the lead acetate it is to be observed that this substance tends to strengthen the color of straw and Panama hats and also to freshen and improve the appearance of white fabrics. The lead acetate is particularly advantageous in combination with hydrogen peroxide, which latter is an antiseptic and tends to retain retain the original color of the article while drying after it has been cleaned. the hydrogen peroxide further removing mildew from fabrics. The oxalic acid is a bleacher and is particularly applicable to remove ordinary ink. rust stains or spots. The sulphur adds color to the composition and like the oxalic acid is a bleacher. but in addition it is also an antiseptic. The rock alum tends to stiffen somewhat the material cleaned and to overcome the tendency of the other ingredients to remove from the material its inherent stabilized character. The sodium sulphite is used to cooperate with the oxalic acid to remove grease, paint and the like and is particularly effective when the preparation is used on leather goods. such as shoes, kid gloves. belt-s, straps and the like, either white or colored. The sodium carbonate is a detergent while the baking soda acts as a stabilizer for the composition and also assists particularly in removing grease. The perfume may be of any character and its sole function is to give the preparation a pleasant odor.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is A cleaning composition, formed by mixing together the following ingredients in the following proportions, approximately one gallon of water, sulphur four ounces, three ounces of oxalic acid, two ounces of lead acetate, four ounces of sodium carbonate, two ounces of bicarbonate of soda, one half pound of sodium sulphite,two ounces of rock alum, three ounces of hydrogen peroxide, and one teaspoonful of perfume.

In testimony whereof I afiix my signature.

STEPHEN D. FRANKO.
